Review Questions for Fetal Pig Dissection, Worm and Frog Dissection, and Digestion

Fetal Pig Dissection

General Anatomy

1. Identify the main body cavities in the fetal pig. What organs are located in each cavity?

   • Describe the dorsal and ventral cavities.
   • List the organs found in the thoracic cavity, abdominal cavity, and pelvic cavity.

2. What is the significance of the umbilical cord in fetal pigs?

   • Discuss the roles of the umbilical arteries and vein.

Organ Systems

3. How does the circulatory system of the fetal pig differ from that of an adult pig?

   • Explain the significance of the ductus arteriosus and foramen ovale during fetal development.

4. Name the major components of the fetal pig's digestive system and their functions.

   • Include the mouth, esophagus, stomach, intestines, liver, pancreas, and rectum.

Biological Development

5. What are the main developmental stages of a fetal pig?
   • Discuss how the organ systems develop and their importance for survival after birth.

Worm Dissection (Earthworm)

External and Internal Features

1. Describe the external characteristics of an earthworm. What adaptations do these features support?

   • Consider segments, bristles (setae), and the clitellum.

2. What are the main structures of the earthworm’s digestive system, and what role does each one play?

   • Discuss the mouth, pharynx, esophagus, crop, gizzard, and intestines.

Circulation and Respiration

3. Explain the circulatory system of the earthworm. How does it differ from that of vertebrates?

   • Discuss the role of the dorsal and ventral blood vessels.

4. How do earthworms breathe? Describe their respiratory system.

   • Explain the process of gas exchange through the skin.

Frog Dissection

External Anatomy

1. What are the distinguishing external features of a frog compared to other amphibians?

   • Discuss the presence of webbed feet and skin texture.

2. Identify the structural adaptations of a frog's hind limbs for swimming.

   • Explain how these adaptations aid in locomotion.

Internal Anatomy and Function

3. Describe the main organs found in a frog's respiratory system.

   • Include parts such as the lungs and skin for cutaneous respiration.

4. What are the primary adaptations of the frog's digestive system for its diet?

   • Discuss the significance of the stomach, intestine, and liver.

Circulation and Reproduction

5. How does the circulatory system of a frog facilitate its amphibious lifestyle?

   • Explain the two circuits: pulmonary and systemic.

6. What methods of reproduction do frogs employ? Outline their life cycle.

   • Discuss egg-laying, tadpole stage, and metamorphosis.

Digestion Overview

Digestive Processes

1. What are the four main stages of digestion? Explain what occurs in each stage.

   • Include ingestion, digestion, absorption, and elimination.

2. How does the digestive system of humans compare to that of the fetal pig?

   • Discuss similarities and differences in structure and function.

Nutrient Absorption

3. In what part of the digestive system does most nutrient absorption occur?

   • Discuss the surface area importance of the small intestine.

4. Describe the role of enzymes in digestion. How do they facilitate nutrient breakdown?

   • Provide examples of key digestive enzymes and their substrate.

Disorders and Health

5. What are common digestive disorders, and how do they affect digestion?

   • Discuss conditions such as GERD, IBS, and celiac disease.

6. How can diet and lifestyle impact digestive health?

   • Explain the importance of fiber, hydration, and regular physical activity.
